Atmosphere- a blanket of air that surrounds the earth Function of the atmosphere 1. It insulates us so that we don’t freeze at night. 2. Its ozone layer protects us from the sun’s ultraviolet rays. 3. It also contains the carbon dioxide needed by plants for photosynthesis, and the oxygen we need to breathe. Layers of the atmosphere Troposphere • Layer closest to the Earth. • Where all weather occurs • The higher you go in the Troposphere the colder it

Warming – Karla Bovell 3.1 Global warming is the increase or rise in temperature of the earth’s atmosphere. Some think it is part of the earth’s natural cyclical variability and some think it is due to the increase in greenhouse gases which trap heat that would otherwise escape from Earth. However, greenhouse gases, such as water vapour, carbon dioxide, methane and nitrous oxide, are an important part of our atmosphere because they keep Earth from becoming an icy sphere with surface temperatures of about

gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die. What is the greenhouse effect? The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car. On a very hot day, the car gets hotter when it is out

Global Warming Global warming is the warming of the earth's atmosphere. For many years humans have been blamed for causing global warming. Global warming, however, can be caused by natural effects. One reason is that the earth is constantly going through periods of warming and cooling. Second the two most abundant greenhouse gases water vapor, and carbon dioxide both occur naturally. Third the earth is not the only

Changes in Earth’s Atmosphere Climate change, better known as “Global Warming” or “Greenhouse Effect” is caused by an emission of heat- confined gases produced by vehicles, industrial development, power plants and deforestation. As these gases build up, they began to over heat the Earth causing our health, environment and economy to be effected. Climate change has become a widespread problem. If we do not protect our nature, climate change will soon ruin the terra firma (land) and irrigation we

metals and agriculture. Lithosphere There are four layers of the atmosphere Thermosphere- Where satellites orbit the earth. Mesosphere- This is where most of the meteorites and comets burn up. Stratosphere- Is where the ozone layer is confined. Troposphere- This is where all animals live; and contains all the earth’s natural air gases, such as Nitrogen, Oxygen and other minor gases. There are four layers of the atmosphere Thermosphere- Where satellites orbit the earth.

the Mauna Loa Observatory, located in Hawaii, is to measure the levels of carbon dioxide in order to determine how much of our atmosphere is comprised of this gas. A long feared benchmark among scientist has been reaching 400 parts per million as it is considered a tipping point from which our planet would be unlikely to recover from for centuries. The Earth’s atmosphere reached 400 parts per million almost 5 years ago in 2013. I specifically remember reading about this when it was confirmed and

that through air pollution we are depleting our ozone bubble that protects our earth. As the ozone depletes it allows higher concentrations of radiation into our atmosphere, thus increasing our overall temperature of the earth and its crust. As the earth’s crust heats up it causes more volcanic activity around the globe, cause the earth’s crust to shift more regularly as we have seen with volcanic eruptions in Iceland and Tsunamis in our oceans. Our arid regions begin to grow annually and smaller
